Most Windows computers do not have Perl by default and one must be installed. Any distribution of Perl should work as long as the required modules are included. The Strawberry Perl distribution for Windows is known to work and is recommended. Downloads are available here:

The Perl scripts should run with any relatively recent Perl interpreter. In some cases, particularly for older Perl releases, you might need to install some required modules, namely XML::SAX and Bundle::LWP (libwww-perl). The procedure to install these modules is system dependent, for most Unix/Linux OSes they can be installed using the package management system. In addition to Perl only network access to the IRIS DMC's web server is needed.

For large data requests installing the XML::SAX::ExpatXS Perl module will significantly increase the parsing speed of XML metadata used by all scripts.
